"All the perfumes of Arabia will not sweeten this little hand. O, O, O!" (LM, 5,1)
- Hyperbole (all - arabia) - indicates the hopelessness of her situation - the crime of regicide cannot be undone and the stain on her soul cannot be removed.
- The suggestion is that even though there is no physical sign of the blood, the smell still remains implying that others will be able to detect what they have done
- "sweeten" - verb - could be seen as LM trying to achieve innocence by reverting back to a feminine state.
- "O, O, O!" -> fragmented speech - reflects lack of control of her own mind, in this scene she used PROSE, rather than blank verse she used in earlier acts, showing again the descent into madness -- repetition, tricolon, exclamation mark - emphasises the distress that LM is going through and her declining mental state.
Semantic field of "perfumes" and "sweeten" have connotations of femininity which are at odds with LM's initial desire to be "unsex[ed]". Represents LM's return to regular, biological, feminine self after feeling the weight of guilt of her action
